zorin OS is detected as Debian rather than Ubuntu

[darkn3rd]

Description

On a fresh install of Zorin OS, the system is detected as Debian rather than as an Ubuntu causing requirement issues when installing a ruby version less than 2.4.

Steps to reproduce

1. Install Zorin OS
2. Intall rvm

gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
curl -sSL https://get.rvm.io | bash -s stable
source ${HOME}/.rvm/scripts/rvm

3. Install project ruby

$ cat .ruby-version 
ruby-2.3.3
cat .ruby-gemset
myproject
rvm install $(cat .ruby-version)

Expected behavior

Healthy Ruby Environment for Ruby 2.3.3 with ssl support for gems like bundler for Ubuntu.

Actual behavior

RVM mis-identifies OS as Debian, and attempts to use debian package names (not Ubuntu) for openssl.
